It is a case of too much money for John Sanderson. As a poor machinist he is happy, but when he perfects an invention and makes $100,000, it goes to his head. He marries Julia Casey of poor parentage, and they set out in great style. They snub Angus McDonald, Nettie Arliss and even Julia's father, Patrick, a delightful old Irishman. Then John begins to speculate in stocks. He was a good inventor but a poor speculator. He goes broke, and must again go back to work in the machine shop. But they take it cheerfully. It was a good time while it lasted. Patrick forgives their snobbery, and Angus and Nettie invite them to \"stand up\" for them at their marriage.
